Application filed March 7, 1907. Serial No. 361,187.

alarm or warning signal of a more or less musical character, controllable at the will of the operator.

My invention also has for its objects simplicity ot'construction, certainty and con trollability of operation, and prevention of accidental sounding by reason of the vibrations of the vehicle or conveyance.

I will now ClGSCIIbG the construction shown in the accompanying drawings and embodying my invention and will thereafter point out my invention in claims.

Figure 1 is a side elevation partly in section of an automobile'showing my invention applied thereto. Fig. 2 is a detail side-elevation, partly in section, showing on an enlarged scale the operating pedal and. friction-wheel whereby operative contact is made with the fly-wheel of the engine. Fig. 3 is a detailplan 'of the pivot of the pedal. Fig. 4 is a detail part elevation and part longitudinal section of the sounding device With its supporting and other related parts. Fig. 5 is a vertical section of the same on the line 5-5, Fig. i. Fig. 6 is a horizontal sectionon the line 6-6, Fig. 4.

The sounding device shown and particularly claimed is a unit or note forming part of the well known hand-operated musical instrument designated an organ-chime. It

comprises musical tubes 7, of which four are shown, of three different sizes, toned an octave apart, with two tubes of the higher octave, these tubes being independently carried by a resonator 11, which is pivotally supported on the casing 10 by a pivot pin 8 between the downwardly extending arm 9 of the casing and the downwardly extending arm 11 of the resonator.

The casing 10 is in the form of an elongated half-round shield inverted over the sounding-device. This casing or shield with its supporting sounding device is rigidly secured to the automobile in any suitable location, for instance, inthe location shown in Fig. 1.

The resonator of the sounding device consists of a tubular sounding board 11, ordinarily made of wood. Arms or rods 12 and the above mentioned arm 11, which receives the pivot pin 8, project downward from the resonator and act in connection with horizontal cross-bars which extend from ari'n to arm and pass loosely through perforations in the lower semi-tubular portions of the sounding tubes 7 and are provided with surrounding rubber sleeves 13 to space the tubes and prevent contact between the crossbars and the tubes. The tubes 7 have arejections or forks at their upper ends which project into suitable openings formed for,

that purpose through the walls of the resonator. Thus, when the resonator is shaken, the forks of the tubes strike the sides of the openings into which they project and thereby cause the tubes to sound.

To provide the vibrating action necessary to operate the sounding device, I provide a shaft 16, vertically arranged and rotating in bearings 17 secured to the casing 10. A worm 18 on the shaft operates the wormwhcel 19 rotating on a stud projecting from the casing. A connecting rod 20 connects the wheel and the resonator.

A flexible shaftnfil, incased in a flexible casing 15, connects the shaft 16 with a friction wheel 21, this friction wheel being adapted to be brought into frictional contact with the flywheel 29 of the engine of the automobile (see Fig. 1). The bearing of the friction wheel 21 is formed in an arm pivoted at 26 to the base 27 secured to the body of the car (see Figs. 1, 2, 3), and the arm 25 is normally held by a helical spring 30 in upper position with the friction wheel away from the fly-wheel. A pedal or foot-plunger 28 slides vertically through a socket in the floor of the car and bears downwardly upon the upper face of the arm 25,

ment of the pedal and the spring 30 controls both the friction-wheel arm 25 and the pedal 28.

To prevent the vibration incident to a vehicle in motion from vibrating and sounding the tubes 7, I provide a damper, which consists of a bar 31 faced with felt or other suitable material (see Fig. 6) and supported by arms 33 projecting upward from the damper-bar 31 and pivoted on lugs 32 of the casing. One of these arms 33 extends above the pivot and is curved to extend over the resonator and is engaged by a helical spring 35 which normally holds the damper-bar against the tubes and thereby normally clamps them. This extended arm 33 is connected to the operating pedal by a cord or wire 36 running over suitable guide-pulleys 34. hen the operating pedal 28 is depressed this cord acts to move the bar 31 away from the tubes and thereby undamps them. Normally, therefore, no amount of vibration of the vehicle can operate to vibrate and sound the tubes, because the spring 35 working through the bar 31 acts to normally damp them. \Vhen, however, the operator desires to sound the alarm, he presses the operatingpedal with his foot, thereby forcing the friction-wheel 24 into contact with the fly-wheel of the engine, which causes the friction-wheel to revolve, which in turn acts through the flexible shaft 23 and the worm-shaft 16 to revolve the toothed-wheel 19. This through the connecting-rod 20 subjects the sounding-device to a vibratory motion which vibrates the tubes and causes them to sound. They are now free to do so, as the dan1ping-bar 31 is withdrawn by the act of pressing the operating pedal into motion-receiving contact with the fly-wheel.

So long as the operator presses the op erating pedal, the vibratory mechanism intermediate the flywheel or other moving pa'rt'of the vehicle and the soundingdevice continues to vibrate and soundthe tubes free fromthe action of the damper. The moment, however, the control pedal is released the vibratory mechanism for vibrating the sounding device is thrown out of operative connection with the moving part of the vehicle and the damper thrown on. This condition continues until the pedal is again pressed or operated. Thus the controlling means whereby the operator causes the alarm to be sounded effects the undamping of the tubes when these means are operated and the damping of the tubes when the operation of these controlling means is terminated.

It is obvious that various modifications may be made in the construction shown and above particularly described within the principle and scope of my invention as defined in the following claims.

I claim 1. A musical tube, mechanically operable mechanism for vibrating the tube and effecting a continuation of the vibration in a single act, a damper normally engaging and damping the tube, and means for controlling the damper for undamping the tube and for controlling the mechanism for vibrating the tube. v

2. A musical tube operable by vibration, a resonator in coeperative relation with the tube, mechanically operable mechanism for vibrating the tube by shaking the resonator which moves relatively to the tube, and means for controlling the damper for damping the tube and for controlling the mechanism for actuating the resonator and tube.

3. In combination with a rotating part of a vehicle, a musical tube, a resonator adapted to vibrate the tube, a flexible shaft, a friction Wheel mounted on the shaft and arranged to engage the rotating part, connection between the shaft and resonator to shake the resonator, a damper normally engaging and damping the tube, and manually-operatable means for simultaneously throwing the damper out ofoperation and moving the friction wheel into contact with the rotating part to shake the resonator.

A musical tube and a resonator therefor, mechanically operable mechanism for oscillating the resonator and shaking the tube, such mechanism including a rotary shaft, the resonator being arranged to engage and vibrate the tube, and manually 0p- .erable means for controlling the mechanically operating mechanism for the resonator and tube.

5. In combination, a musical tube, a rotating part of a vehicle, a flexible shaft, a friction wheel mounted on the shaft and ar ranged to engage said rotating part, crank and-rod connections between theshaft and the tube to vibrate the tube, a damper normally engaging and damping the tube, and manually-operable means .for simultaneously throwing the damper out of operation and moving the friction wheel into contact with the rotating part to sound the tube.

In testimony whereof I have afiixed my signature in presence of two witnesses.
